(S/E) The start is the small car park at Ogwen Cottage (grid ref. SH649603) on the south side of the A5 between Bangor and Capel Curig. In fine weather and at weekends parking can be in short supply. National Park information is available with up to date weather forecasts and refreshments are also available here.
After parking walk over the Ogwen Falls footbridge and follow the clear stony path. After a short way the path divides and here you bear right and continue across to the shores of Llyn Idwal. Reaching the lake, turn lefty and follow the clear path in a clockwise direction around Llyn Idwal. You soon realise the rugged nature of this rocky amphitheatre and you make steady progress along the path, which initially stays close to the lakeshore.
(1) The path then gains some height at the southern end of the lake and bears right under Devil's Kitchen, a rocky mass of huge boulders and scree. The path then turns right again and joins the path descending down through the Devil's Kitchen to follow the western shores of the lake. A circuit of the lake is soon complete and you need to take the path on your left that follows the outward route back down to Ogwen Cottage(S/E).
